I was really impressed with the homemade ginger ale, which also contained lime juice and mint. It was like a ginger mojito, minus the alcohol - very refreshing. I thought it was neat that the menu specifically stated which items could be made meat-free and dairy-free.
After reading all of the other reviews, I wish that I had gone with the beet burger for my entree. Instead I got the tomato cheese flatbread minus the cheese (with balsamic-glazed onions instead). The balsamic-glazed onions were great, but I was a little annoyed that they still charge extra for them even when you leave off the cheese. I ended up paying $9.50 for a thin pizza crust topped with tomatoes and a few glazed onions, while if I had ordered the dish as it was listed on the menu, it would have been covered in two types of cheese and cost $2.00 less.
That said, aside from my pricing complaints, I had a very enjoyable meal at Northstar Cafe. I would give them a rating of "great" if they were willing to make substitutions for vegan meals (rather than just leaving out ingredients).
